Samsung patents method to reduce noise in 5G signal processing

Samsung has filed a patent for a way to improve how base stations measure the quality of wireless connections. The system analyzes signals from phones to estimate background noise and calculates a specific error metric to refine the data.

Why it mattersThis is a technical improvement to how cell towers process data, which may help maintain stable connections but is unlikely to be visible to everyday users.

In the filing’s own words

Methods and apparatuses for time-domain-based channel estimation in OFDM systems in wireless communication systems. The method of a base station comprises: receiving, from a user equipment (UE) via a set of antennas, uplink signals including at least one of sounding reference signals (SRSs) or demodulation reference signals (DMRs); identifying time-domain channel estimation (TDCE) for each of the uplink signals, wherein a noise power is estimated to identify the TDCE; removing a noise floor from the identified TDCE; and performing, based on the estimated noise power and an estimated signal-to-noise ratio (SNR), an operation to obtain normalized mean square error (NMSE) for the TDCE.

What exactly they claim (claim 1)

1. A base station (BS) in a wireless communication system, the BS comprising: a transceiver configured to receive, from a user equipment (UE) via a set of antennas, uplink signals including at least one of sounding reference signals (SRSs) or demodulation reference signals (DMRs); and a processor operably coupled to the transceiver, the processor configured to: identify time-domain channel estimation (TDCE) for each of the uplink signals, wherein a noise power is estimated to identify the TDCE, remove a noise floor from the identified TDCE, and perform, based on the estimated noise power and an estimated signal-to-noise ratio (SNR), an operation to obtain normalized mean square error (NMSE) for the TDCE.
